New to the forum and scanned down several pages to see if there were any comments relative to my question before posting this... I have been trying to find a reloading mix to solve a grouping issue with my 6.5. I have tried every version of factory shell, including Superformance, in every weight and style of bullet available and have not been able to group less than 1.75" at 200 yds. I reload and have been trying different mixes there too, best group with 123gr A-max and Varget. Question is for you: Do you feel that the 22" barrel works best with light bullets at a speed over 2900fps (Superformance) or with a heavier bullet at slower speeds like 2700, once again Superformance?
